Extinction: past, present and futurefuture

Can we move beyond recording extinctions, andrecognising threatened species, to prediction and to

designing preventative actions?

Bats as indicators?

Represent a fifth of all mammalian biodiversity

Occupy a wide range of niches

Provide a number of ecosystem services

Sensitive to climate change as depend on nocturnal flyinginsects (themselves sensitive to changes in temperature)

Sensitive to pollution through poisoning of their insect preybase

Why are bat indicators important?

Policy Implications and Profile Raising

Why just birds and butterflies?Raise profile on international biodiversity agenda

Fund raising mechanism for long-term monitoring

Importance in Landscape Planning

Landscape-wide indicators of ecosystem function

Facilitate effective planning of sustainable development

Indicator of public involvement and wider appreciation ofbiodiversity


9/45

A monitoring program needs

Long-term records generated with a common protocol

Sustained funding for personnel and resources.

Successful models train volunteers in monitoringprotocols, who then donate their time during the annualsurveys.

However, there is no global monitoring program forbats and no agreed upon protocols for evendeveloping one

EUROBATS

Established in 1994 currently 30 Parties (UNEP 2001)

Agreement set up under the Convention on MigratorySpecies - to protect all 45 species found in Europe

Advisory Committee set up PanEuropean monitoring and

action plans to address declines, recognising importantsites, esp. of migratory spp.

Comprehensive international program for endangered bat-

species in Europe

Conservation of Populations of EuropeanBats

Indicator Bats Program - iBats

To generate monitoring data on bat species distributionsand abundances across the world to evaluate the effect of

global change on biodiversity loss.Collaborate with existing national and international bat

monitoring projects

Initiate new bat monitoring projects

Develop and implement novel monitoring protocols

Provide a centralised common database to store and analyseglobal bat monitoring data

Disseminate protocols and results through an interactive web dataportal (www.ibats.org.uk)

Monitoring Irish bats acoustic car transects

The first pilot in 2003 with the newly formed Bat ConservationIreland - 7 survey teams

2004 - 17 survey routes

2005 - 21 routes with 40 volunteers

2006 - 26 routes with 59 volunteers

Adopted by the Irish Government as the official monitoringtechnique for 3 species

BCIreland has been expanding to more intensive monitoringtechniques.

UK Results 2005-2006

A total of 6911km (3573km 2005; 3338km 2006) of roadwere driven.

A total of 10147 (4719 bats 2005; 5428 bats 2006) wererecorded from 10 bat species/species groups and a total of910 (399 2005; 511 2006) other mammal species were

recorded from 28 species groups. Bats encountered included common, soprano and

Nathusius pipistrelles, Leislers bats, noctules, serotines

and Myotis spp. The top seven other mammal species encountered were:

rabbits; bats; foxes; hedgehogs; mice; hares; and badgers.

Differences in community composition

Soprano batsencountered morefrequently inScotland and westof Ireland thanEngland or Wales.

Is this linked toclimate sopranosforage on waterborne insects?

Is it the sameacross Europe?

Global iBats - SWOT

Strengths Standardized protocols Simple data collection methodologies

Public involvement in biodiversitymonitoring

Effective use of limited resources Can deliver regional, national and

international monitoring Web portal acts to manage data, people

and projects

Builds capacity using existing networks Low cost

Global iBats - SWOT

Weaknesses Technical issues:

large data files,

equipment integration, web portal development

Analytical issues: sound analysis subjective and

lengthy, call identification problems, lack of call libraries

Data input limited to this methodology


44/45

Global iBats - SWOT

Opportunities A global bat monitoring system Mass public participation

Profile raising for bat conservation Understanding global distributions of bats

and future threats Global call libraries Systems for automatic identification and

analysis

Threats Data collected incompatibly Unsustainable monitoring not enough

power to detect trends
